BUNSEN BURNER.

SPECIFICATION forming part of Letters Patent No. 612,959, dated October 25, 1898.

Application iiled February 26,1898. Serial No. 671,769. (No model.)

To all whom, it may concern:

Beit known that I, JAMES P. WILSON, a citizen of the United States, residing at Newark,

in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bunsen Burners7 of which cipally applicable in that variety of burners employed for producing an incandescent illuminant, as in the well-known lVelsbach burners 5 but it may be applied with equal advantage in any form of Bunsen burner, whether employed for lighting or for heating purposes.

The object of my invention is to provide the burner with a simple, cheap, efficient, and reliable means by which the ilow of gas and the flow of air to the commingling tube or chambermay be simultaneously regulated and properly proportioned by the adjustment of a single piece or adjunct of the burner.

The necessity of a single adjustment of the kind referred to is due to the varying quality of the different gases in use as well as to the different pressures under which such gases are consumed. v

My invention therefore consists in a single instrumentality in connection with a Bunsen burner which by a single adjustment shall control and regulate or proportion the admission of both gas and air, so that as more gas is admitted less air will be admitted, and the reverse, as will be herein irst fully described, and then pointed out in the claim.

Inl the accompanying drawings, forming part of this speciiication, Figure 1 is a view in elevation of a Bunsen burner, showing my regulator applied in connection therewith, the regulator being shown as adjusted to the limit which will preclude the admission of air and open the gas-passage to its full extent, the dotted lines indicating the application of the improvementin connection with the frame of a convenient form of incandescent gaslamp. Fig. 2 is a vertical sectional view of the burner shown in Fig. l, the parts being in corresponding position; and Fig. 3 is a like view wherein the regulator is turned 0r moved to the other limit of its adj ustmentthat is, to open the air-inlet passage to its fullest extent, at the same time completely closing the gas-inlet. Fig. 4 is a horizontal section on a plane through line a: xof Fig. 2, and Fig. 5 is a horizontal section and plan view on a plane through vline y y of Fig. 3.

In all the figures like letters of reference wherever they occur indicate corresponding parts.

A is the base of the burner structure through which gas is admitted, and on this is sustained the commingling tube or chamber B, within which the air and gas are mixed before being consumed. Tube B and base A are connected through the medium of suitable arms, as a a, between which air may freely enter to be drawn in at the lower mouth of tube B when that mouth is open;

C, Fig. 1, represents the frame of an incandescent gas-lamp, which may be of any pattern and with which the Bunsen burner may be used; but the improved burner may be used for any other lighting or heating purposes and generally in any sit-nation where it will be found available.

To regulate the issue of gas from the burnerbase and at the same time the inflow of air to the base of tube B, it is my purpose to employ a single piece, the same being arranged to accomplish both functions simultaneously. Such a piece is shown at D, the same being threaded upon the burner-base and movable thereon to any desired point between the limits where it will either cut oft all the air or all the gas. In this form the lower mouth of the commingling tube may be more or less flared, as indicated, or otherwise fashioned as may be desired, and the top of the regu lating-piece D should be correspondingly formed, so that when turned to its seat against said mouth it will exclude air therefrom.

At b on base A is a conical projection, and around this are perforations, as at c, through which the gas may issue, and in the upper part of piece D is an opening of size calculated to lit the cone b when piece D is turned, as in Fig. 3. When so turned, the regulator IOO will arrest the iiow of gas, and between that position and the one shown in Fig. 2 the reg-ulator may occupy any position.

It will be seen from a consideration of the foregoing and of the construction shown that as more gas is admitted to the comminglingtube less air is admitted, and vice versa, soj

that by use of the single regulating-piece the flame or the mixture to be burned may be proportioned to secure the desired results and this by but a single adjustment.

be the quality of the gas the regulator-piece has only to be turned so as to secure the de- No matter what maybe the pressure or what may Having now fully described my invention, what I claim' as new therein, and desire to secure by Letters Patent, is 1 In a burner of the character herein set forth, the combination of the burner-base, the commingling tube or chamber mounted upon arms yconnected with the base, the stationary cone, and the regulating-piece threaded upon the base and perforated to iit the cone, said regulating-piece being arranged to simultaneously govern the flow of gas and the admission of air to the lower open mouth of the commingling-tube, substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two Witnesses.

Dated New York, N. Y., February 24;, 1898.
